- 4X – The central cursor area of the image is zoomed to 4 times with full screen.
- PIP – The main screen displays the original screen with PIP images magnified by a factor of two are displayed in the window above the screen.
Color Palette
The riflescope can be set to display infrared images in a variety of colors making it easier for users to observe and identify targets. Palette options include:
white hot/black hot/red hot 1/red hot 2/red hot 3/green hot and blue hot.
Brightness
There are ten levels (1-10) of image brightness that can be adjusted to user preference.
Contrast
There also are ten levels (1-10) of image contrast that can be adjusted to user preference.
Ranging
The ranging function can estimate the distance of a target by a known target size. Three examples of targets are available on the device as a reference: 0.25m/0.8 ft., 0.5m/1.6 ft., 1.8m/5.9 ft., and real-time display of distance information of the three animals.
Operation
- Press the Roller-Button to enter the menu, select the ʻRangingʼ and press the knob to enter the ranging function
- Align the lower horizontal line with the bottom of the target image, rotate the Roller-Button up or down to change the width between the upper and lower horizontal lines until the upper horizontal line is aligned with the top of the target icon. At this time, the distance can be calculated and displayed automatically.
- By comparing the target size with the three reference animal sizes, the user can roughly calculate the distance of the target.
Zeroing
Before going afield, the riflescope and thermal imager must be sighted-in and the reticle zeroed. Zero-calibration can be performed and saved for six different models.
For each model, only one zero calibration position can be stored.
The zero-calibration distance of the thermal imager is automatically set at 100m, but users may select the zero-calibration distance to their own preference (i.e. 50 or 200 meters/yards). The principle of zero calibration for the thermal imager is that the aiming point on the reticle line is moved to the actual point of impact
Zero-Calibration Process
- Press the Roller-Button to enter the main menu and rotate the knob to select “Advanced”
- Press the knob to enter “Advanced Menuʼ and rotate the knob to select “Model Select.” Choose the model number and select Return to return to main menu
- Rotate the hand wheel, select zeroing;
- Press the Roller-Button and enter the Zero- Calibration Distance selection
- Aim at your target and shoot a group of 1-3 shots. Calculate the distance from the actual point of impact to your aiming point
- Select the “X” or “Y” direction and move the center of the reticle to the actual point of impact. To do this, rotate the Roller-Button to select the “X” or “Y” axis in the box. Press the knob to select to enter adjustment
- Rotate the hand wheel, move the aiming point in the center of the reticle line to the actual point of impact
- Shoot another group and continue to adjust the position of the reticle until your actual point of impact hit your aiming point
- To complete zero calibration, select “Save” and exit. If do not want to store the zero-calibration position, select exit without saving and exit Zero-Calibration.
Advanced Menu
Enter the “Advanced” menu, in order view the reticle details, the reticle is automatically adjusted to the center of the screen. When you exit this menu, the reticle is restored to its original position.
Model Select
The thermal imager store zeroing positions of six models. If the user has stored zero-calibration positions of several models, it is necessary to select the model of the current equipment. The thermal imager will automatically adapt to the selected model, to precision accuracy.
- Enter the “Advanced” menu, select “Model select, choose the desired model number and exit.
Reticle type
The thermal imager is equipped with a selection of 10 reticles. Reticle number 1 is shown by default. Reticles 2 – 10 can be selected with the Advanced Menu.
- Enter the Advanced Menu, select ʻReticle Typeʼ, select from 1-10. The selected reticle will be displayed in the center of the image. After zero calibration, the user can use the center of the reticle line to observe and aim.
Reticle Color
The reticle can be set to black or white. To choose a color, enter the “Advanced” menu, select “Reticle Color”, chose the color and exit.
Setting Menu
When you enter the “Setting Menu”, the reticle is hidden. When you exit this menu, the reticle will be displayed.
Calibration Mode
The thermal imager can be set with different calibration modes: automatic calibration, scene calibration, and shutter calibration. In scene and shutter calibration, you need to exit the menu bar and press the Power Button to perform the calibration action.
- Auto – The device automatically corrects the image quality without any action
- Scene – The user manually corrects the image quality as needed, and the lens cover needs to be attached before calibration
- Shutter – The user manually corrects the image quality as needed and the device shutter closes for calibration
Picture-In-Picture (PIP)
In the Zoom-In mode, the position of the PIP window can be adjusted. The available positions are left, middle, and right. You can also turn the PIP window off. When the PIP window is off, the zoom mode cycles through 1x/2x/4x. When the PIP window is on, the zoom mode cycle is PIP/2x/4x
